Non-Uniform Rational B-spline (NURBS) is often used to construct the free-form boundary representation of threedimensional objects. In this paper, we propose a method for mechanical analysis for deformable bodies by combining NURBS geometric representation and the Galerkin method. The NURBS surface bounding a 3D body is extended to a trivariate NURBS solid by adding another parametric domain represented by additional control points. The displacement field of the body is constructed using the NURBS shape representation with the control point being the generalized coordinates. The interpolated displacement field is directly used to facilitate finite element formulation. In this manner, traditional FEM meshing is not required. In this work, the NURBS-FEM is applied to skeletal muscle modeling. Muscle is modeled as anisotropic, active hyperelastic solids. The directions of the contractile fibers can be uniform or along the tangent direction of NURBS curves. Typical contractive motions of isolated muscle are simulated.

Since humans are creators and users of artifacts and processes, and are constrained by limited resources, a sustainable approach with human element in the center of the development cycle is vital today. Managing and understanding technical and analytical issues about human element in design process is a core challenge for practitioners to develop and improve design strategies that serves to accommodate human needs, abilities and limitations. Although attention has increased in recent decades, direct progress towards a sustainable product development is still not apparent. Methods for sustainability are mostly applied as post-processing activities to safeguard nature, however a pro-active approach is necessary. A sustainable Human Centered Design platform provides an alternative approach to deal with the degeneration of the ecology while providing alternative criteria for considering customer requirements. This paper focuses on improving product design by considering Human Factors as a medium to integrate Sustainability and Human Centered Design strategies. The emphasis in this framework is to introduce Human Factors aspects of product design early in the concept generation phase, provide a modular platform to allow integration of domain knowledge and technologies and to enhance the product development, and overall well being of human element in design cycle.

“…Literature review shows that engineering design practices that utilize DHM have the potential to enable engineers to incorporate HF/E engineering principles earlier in the product design process (Chaffin, 2002;Demirel and Duffy, 2009). This helps organizations design safer and efficient products while optimizing the productivity and cost (Yang et al, 2004). Since sustainability and the human element are evident components of every aspect of the life, DHM has potential to provide systematic support in bridging these disciplines.…”
